Hello Kent,<br><br>I actually was just presented a response by another user, Cramer Silkworth. I am unfortunately not too familiar with Radiance, but here was the response.<br><br>Best regards,<br><br>Matt Duffy<br><br>"<font size="-1"><font>Both trnsys and radiance are very powerful simulation engines.
Though graphical interfaces for both exist (built-in with
Trnsys, in Simulation Studio, and as add-ons for Ecotect and
Sketchup for Radiance), they are most powerful when used like a
programming language - ie, modifying their text input files
directly. This gives you the most control, and once you learn
their syntax, I'd say easier than the graphical interfaces.
Especially for parametric studies.<br>
<br>
If I were to want to couple radiance and trnsys for a project,
I'd be using DaySim as a front-end for radiance. Version 3 is on
the verge of final release (workable beta is available now - <a class="moz-txt-link-abbreviated" href="http://www.daysim.com/" target="_new">www.daysim.com</a>),
and it's free. It essentially runs radiance for your geometry in
an annual simulation (with weather data), can handle active
shading and electric lighting, and has numerous outputs -
including one intended for coupling to trnsys. Then you just
need to set up your trnsys model to read this file from daysim
(it comes with a generic data file reader component), and then
you use your results to modify your lighting power accordingly
(or whatever variable you want to respond to lighting
conditions). I can't say I've used too many other daylight &
energy modeling programs, but I'm fairly confident there are
very few if any other programs out there that can handle such a
coupling as detailed as trnsys & daysim/radiance can. I've
heard of it being done with eQuest, but I think the eQuest side
of things is a bit limited. There are other daylight simulation
programs as well, but Radiance is always talked of as being the
industry 'standard.'"</font></font><br><br><br><br>
